Abstract
A display device, a display panel, a driving method, and a gate driver circuit. Threshold voltage sampling times of driving transistors are changed by varying pulse widths of gate clock signals depending on horizontal lines. Luminance uniformity of the display panel is improved, even in the case in which horizontal line-specific driving voltages have different voltage drops.
